MULTIPOLAF, SWTGH.

10 all whom t may concern:

Be it known that l, PAUL Sinner, a citizen oi the United States,residing at lllcrcester, in the county of llVoii'cester and State ofMassachusetts, have invented a new and useful Multipolar Switch, ci'which the ollowing is a specification.

The object oi this invention is to provide a new and improvedmulti-polar switch by which many permutations or `combinations ofvarious circuits can easily be obtained.

The switch has been especially designed for use in connection with atransformer, al-

though the same is capable of other uses.

rlhe invention is illustrated in the accom-` rtrating the different waysthe switch may be set.

The invention will be best understood by lirst giving a detaildescription 0f the switch, and to follow this description referenceshould be had to Figs. 2 and 3 oi' the drawings.

Referring to the same and in detail, A

designates the switch body or casing which is preferably made incylindrical shape with a bottom plate C' designates a circular `rib orpartition which is secured inthe body so to divide the same into anouter annular chamber D, and an inner circular chamber E. l? designatesa cover which may be secured to the body by any desired means.

A shaft G is soclreted in the bottom B and has a wing G secured to whichis a bottom distributer bar H made of conducting material, such ascopper, the shaft G preferably being made of insulating material.

A bushing I is fitted on the shaft G, and the same is provided with awing I, secured to whichis an upper distributer bar J preierably madeof: copper, the hub I being made of insulating` material.

A knob or handle K is secured on the shaft G and a knob or handle L issecured on the bushing I, these knobs or handles being provided forsetting the switch.

Serial No. 455,907.

three armed iframe or segment N is ci "ried by the distrilniter bar Hpreferably by pivoting the same thereto and bv holdthe same in position.relatively.l to the g l'l by a spring O which is arranged to be irameagainst a stop The trame is preferably made oit insulating material, andcarries three connecting pieces N, N and N2 preferably made of copper.

10 desigi etes' the binding Vpost for the leading-in wire, .and 11` thebinding post for 1 7 p Li a' leading-out wire.

Contacts 12, 18, 14 and 15 are secured to tnepartition C in position sothat one end oit the distributer bar H will cooperate with the surfacesthereof next the bottom B. The contact 12 is connected to the post 10,and the contacts 12, 18,14: and 15 are connected together by a bus-bar16 arranged on the bottom of the switch.

` Contacts 17,18, 19 and20 are also secured to the partition C so thattheir sur fafces next the cover F will come in a. plane to cooperatewith one end of the distributer bar J. rlhe post `11 is connected to abus-4 bar 21 and the contacts 17, 1.8, 19 and 20 are connected to saidbus-bar.

Contacts 22, 28, 24- and 25 are connected posits side of the switchrelatively to the contacts ilireviously described, these contants havingtheir surfaces next the bottom B oi the switch set in a plane so thatthe other end oi. the distributer bar H can cooperate therewith.

.i'lnother set of contacts 26, 27 28 and 29 is also carried by this partof the partition C, the upper 'aces thereot' being set in `a plane sothat the other end ot the distributer bar il can (3o-operate therewith.

The vcontact 17 is provided with a stop 170 and the contact 2O isprovided with a stop 20() to limit the motion of the distributer bar J,and the contact 22 is provided with a stop 220 and the contact 25 with astop 250 to limit the motion of the distributer bar H.

` The contacts 26 and 28 form a pair of con tacts or in other words theyare arranged relatively to each oth r so that when the connecting pieceN is in the position shown 1n Fig. 2 they will be electrically connectedtogether. The contacts 28 and 25 also form a pair of contacts arrangedso that when the connecting piece N2 is in the position shown in Fig. 2they will be connected together. The contacts 2( and also will beconnecte/.1. together when the connectingpiece N occupies the positionat which the connecting piece N is shown in Fig. 2, and the contacts 28and will also be conn nected together when the connecting piece Noccupies the position which N 2 occupies in Fig. 2.

The contacts '12, '13, 1 4.; and l5, and 17, 1S, 19 and 20 are set at aslightly greater distance 'from the center so that the contact pieces N,N and N2 will not co-operate therewith.

The contacts 22 and 26 are connected to a circuit l; the contacts 23 and27 to a circuit the contacts 2% and 28 to a circuit et; and the contacts25 and 29 to a circuit 8, as illustrated in Fig. l.

in the specific application shown of my switch, circuit l includes aprilnary winding P on a transformer T; circuit 2 includes a windingl P2on the transformer; circuit 4t includes a winding 3i on the transformer;and circuit 8 includes a winding P8 on the transformer. These windingsmay be arranged in the ratio in which they are above speciied; that is,relatively as l, 2, 4 and 8.

This is a convenient arrangement tor get ting a number ot permutationstor connecting` the coils in series. These permutations can be easilyfollowed by referring to the second sheet of drawings, and byconsidering the distributer bar H as controlling the 1' ntlow oit thecurrent, and the bar .l the outflow oi the current.

Thus in Fig. lcoil l is connected; in 5 coil 2 is connected; in Fig. 6coils l and 2 are connected, the connecting piece N joining them inseries; in Fig. 7 coil 4 is con* nected; in F ig. 8, coils 2 and 4 areconnected, connecting` piece N connect ng these coils in series; in Fig.9 coils l, 2 and 4 are connected, connecting pieces N and N connectingthese coils in series; in Fig. l0 coil 8 is connected; in Fig. ll coilss and 8 ar connected, connecting` piece N connecting these coils inseries; in Fig. l2 coils 2, 4 and i3 are connected, the connectingpieces N and N connecting these coils in series; and in Fig. A3 coils l,2, l and 8 are connected, connecting pieces N, N and N2 connecting thesecoils in series.

Thus with the coils arranged in the ratio 'ncviously describech thewindings of" the trai former may be connected in any one o!" memultiples Il, 2, El, 1 -f6, 7, 8, 12, ll and lf3.

This terms a desirable switch I'or changing` Vthe voltage fn'' theprimary winding oit a traustormcr. lit high voltages are to be l'mndledthe switch can be :filled with oil.

il: desired the secondary winding oit the trans former inabe arranged ina similar 'that may be divided into coils S, "t and tig, and these maybe connected controlled by another one of my ches as will be readilyunderstood by rej to l ot the drawings.

g two switches in this way a great iiien. voltages can be obtained. Iswitch may be applied for other uses.

The details and arrangements herein shown and described may be greatlyvaried by a sl'filled electrician without departing iii/:om the scope ofmy invention as expressed in the claims.

Eat/'ingr thus fully described my invention what l, claim and desire tosecure by Letters-patent is l. lin electric switch having two seriesoi'v contacts arranged in pairs, two distributor bars cooperatingtherewith, and a Contact pi ce carried by one oit the distributer barsfor connecting the contacts ol: each pair.

2. in electric switch consisting of a series of contacts arranged inpairs, a distributor bar ior cooperating with one set of contac'ts ot'the pairs, another distributer-bar co-operating with the other set ofcontacts 't the pairs, and a plurality of connecting iieccs carried byone ot the distributor bars ,wr connecting the contacts making up thepairs.

3. in electrical switch comprising two series olf contacts arranged indifferent planes, a distributor bar coacting with the contacts arrangedin one plane, a distributer bar lco-icting with the contacts arranged inthe other plane, and a plurality of connecting pieces carried by one. ofthe distributer bars ttor connecting the contacts making up the pairstogethen i testimony whereof I have hereunto a'f- :ined my signaturePAUL SIBLEY.
